Vitamin D

Protecting the skin through the use of sunscreen is essential when it comes to reducing the risk of cellular damage from UV light. Unfortunately, the use of sunscreen with an SPF of 15 or higher inhibits the skin's ability to synthesize vitamin D - a critical nutrient involved in bone health and immune function, among other benefits. Thus, when protecting the skin by applying sunscreen, it is equally important to keep in mind alternative ways for ensuring adequate blood levels of vitamin D. Foods like salmon and fortified milk provide a moderate amount of vitamin D and can be a good way to meet your requirement if you consume multiple servings of each per day. For the many people who don't get enough vitamin D through the diet, taking a daily vitamin D supplement can be a great way to fulfill your need for this very important nutrient.

Maintaining Vitamin D Levels

According to the National Center for Health Statistics, approximately 70% of all Americans have low levels of vitamin D. Emerging evidence suggests that vitamin D may play a role in promoting glucose tolerance. Nutritional supplements can be a convenient and beneficial way to prevent vitamin D deficiency and promote blood glucose management.
